Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model embodiment is described further:
Such as Fig. 1, Fig. 2, Fig. 3, shown in Fig. 4 and Fig. 5, the utility model discloses a kind of new pattern creepage test button device, it includes housing 1, it is provided with movable contact spring 3 in described housing 1, in the downside being positioned at movable contact spring 3, static contact spring piece 4 is set, it is provided above test button 2 at movable contact spring 3, described test button 2 includes button portion 21 and action bars 22, guide part 11 and limiting section 12 it is provided with in described housing 1, described button portion 21 is arranged in described guide part 11, and can coordinate along guide part about 11 sliding, described action bars 22 is through upper contact with movable contact spring 3 after limiting section 12.The outer surface of button portion coordinates with guide part sliding, plays the effect of guiding, can solve the problem that the crooked phenomenon being likely to occur when test button 2 moves up and down simultaneously.And it is arranged on the limiting section 12 bottom guide part, the most i.e. play the effect of guiding, test button can be played again spacing effect, it is to avoid test button pressing excessively causes test button to drop into the phenomenon generation of housing.
On described limiting section 12, the position of the action bars 22 of corresponding test button 2 arranges spacing hole 121, and this action bars 22, through upper surface with movable contact spring 3 after spacing hole 121, plays effect of pressing movable contact spring, and spacing hole also can play the effect of guiding simultaneously.
Described spacing hole 121 both sides chamfering forms inclined-plane, facilitates the action bars of test button to insert when mounted so that operation button is by more convenient during outer installation inside.
Described spacing hole 121 both sides project upwards formation boss 122, change boss can spacing with the operating portion of test button coordinate, and the distance between itself and guide part occurs less than the length of the button portion of test button, the phenomenon that can effectively avoid test button pressing excessively to fall into housing.
The both sides of described button portion 21 arrange the first back-off 23, described first back-off 23 and housing snap-fit engagement, directly stick into housing from top to bottom, assemble up convenient and swift, simultaneously when by outer installation test button inside, this first back-off 23 directly with housing snap-fit engagement, it is possible to avoid it to come off, effective ensure the fastness after the installation of this test button.
Described static contact spring piece 4 one end bending, and bending is in and is located at first and fixes axle 13 side, described static contact spring piece 4 is positioned at the one end below bending part and the first draw-in groove 16 snap-fit engagement being arranged on housing, described static contact spring piece 4 is positioned at that the one end above bending part is spacing with the limited block 15 being arranged on housing 1 to be coordinated, and first draw-in groove, limited block and first fix axle and be fixedly installed by static contact spring piece, it is to avoid it comes off.
Described first fixes axle 13 side is provided with the second back-off 131, and after installing static contact spring piece, static contact spring piece can be blocked by this second back-off 131, prevents its landing or drops so that static contact spring piece fixing relatively reliable.
As shown in Figure 6, the bending of described movable contact spring 3 forms quiet end 31 and moved end 32 respectively, the bending part of described movable contact spring 3 is arranged on second and fixes axle 14 side, and its quiet end 31 is plugged in the second draw-in groove 17 of housing, upper end, described moved end 32 contacts with limiting section 12, and described moved end 32 has the second position that test button presses for 2 times the primary importance contacted with static contact spring piece and test button reset not to contact with static contact spring piece.Axle 14 is fixed in dependence second simultaneously and the second draw-in groove 17 makes movable contact spring constitute the lever that one end is fixing, and its moved end is as the movable end of lever, can be up and down, thus realizes contacting and discontiguous switching with static contact spring piece.
3rd back-off 18 is set in the outside of described housing 1, is used for fixing movable contact spring, it is to avoid movable contact spring comes off.
Upwardly form jut 33 on described moved end 32, and described jut 33 is placed on the path that test button moves up and down so that the stress point of moved end is the most firm, be not susceptible to deformation, improve the service life of movable contact spring.
Described movable contact spring or static contact spring piece coordinate with wire riveting, after movable contact spring and static contact spring piece first being riveted with wire, are installing, and can fix wire, it is possible to ensure the reliability that both connect, improve production efficiency simultaneously in the way of avoiding using welding.
Embodiment is not construed as restriction of the present utility model, any based on spirit improvements introduced of the present utility model, all should be within protection domain of the present utility model.
